GRAIN SHOCKER.

Application filed September 2G, 1921.

TocZZ fic/lima it' 72mg/ concern.'

lie it known that l.j RAY B. (lnun'r, a citiz/.en ot the United States, residing` at .llrecltenridee7 in the county of Caldwell and .tllate of' Mssonri, have invented certain new and nseiinl improvements in `Grain Slhoclqers, of which the following is a speciiieation.

.Tl/ly invention relates to `.rain shockers ot a character adapted to be coupled to and driven with a grani binder. said shocker receiving the bound bundles oi? grain 'from the binder. .torining said bundles into a shock, binding;` said shock, and then leir ositing the shock upon the ground 'in a stand ing' position.

The invention also embodies mechanism,`

for loner-ing the shock in order to assi..l in depositing the` same squarelynpon its butt into the stub-ble, said mechanism bc-` ing` automatic and requiring;` no attention on ,the part ot the driver of the binder.

The invention alsoA provides means tor depositing); cap bundles with each shock for protection oit the latter against the Weather `while stai'iding;` in the eld.

Further objects and advantages ot the invention will be set forth in the following' detailed description and the appended claims, reterencc being` had to the accompanying drawings, in which Fin'. l is a `side elevation oi the shocker with some parts removed.

Fig. 2T is aibroken end elevation partlv on line on line o a spiral spring for turning the spools in a direction to wind cablesthereon.

In carrying out the invention, I employ a 'frame embodying parallel longitudinal members 2, a cross bar 4 fixed to the rear ends of rsaid longitudinalmember 2, and braces 6 extending'y fromthe rear portions of the longitudinal members 2 to the ends of said crossbar 4. The fframe is mounted atits rear-portion'upon `two casters 8 and y at its forward portion upon a caster l0, the

spindle. of which latter is swiveled in the bearing '12 at one end `of atransverse bar 14 connected by a pivot 16 tothel frame A of ..the binder, a'portion of which latter is disclosed by'Fig. 6.

The bar 14 extends beneath the frame and `is connected-by' a Cpivot 18 to a pair of op-V positely disposed members 20, depending from a plank 22sec'ured to the two longitudinal members 2 of the-frame by transverse U-shaped bars 24. 'By thusv mounting the caster l0 it ,is 'free to move vertically `oveiwuneven ground independently of the grain binder frame to which the shocker is connected by' a draft bar 26 and a brace 28,1whielrlatter coactswvith the bar 14 in hold-mg 'the shocker'in'proper relation to the delivery apron C ofthe :grain binder.

The frame of the shocker is reinforced by atracliiconsisting of two oppositely-disposed v parallel ralls spaced `slightly above theV longitudinal'frame members 2l and fixed to the' upturned ends of the transverse bars 24. Said rails 3() consist preferably 'of channel bars above'which similar bars 32 `are sup ported'rin inverted position by the transverse bars 24 to prevent'therear rollers of the'fbundle carrier, 'hereimrftcr described, from leaving` the rails 30.

The channel bars 32 are surnunnitml by a curved track consisting oftn'o vop]' )ositelydisposed rails '34, which extend rearwardly and upwardly to an almost perpendicular position. 'lhe curved rails 34 'are,preferably, made of channel bars and are fixed to superimposed frame men'ibers '36, `38, 40 and 42. Thecurved rails 34 are paralleled by a pair of reversely disposed channel bars 44 which are also secured tothe frame mem- =bers 36, 88, and 42j. to prevent the' forward rollers of the bundle carrier from leaving said rails 34. The frame members 38,-

40 and 42,r are arranged in pairswvliich are spaced apart as disclosed by Figs. ll to 13,

' Ithe bnndleslto the shoclc forming arms 4G,

andeoi'nprises two end members 50 spaced apart land-united 'at their upper terminals by a yoke 52, a transverse end member 54, a longitudinal bar secured at one Aend to one oft-he end members 5() and at its opposite end to the transverse endmember 54, a rock shaft 58 spaced beneath `the bar 5G, and superimposed rock shafts and ($2. The 'rock shafts 58, G0 and 62, are journaled in the respective end members 50 and the transverse end members 54 andv constitute the `two longitudinal sides oft-he carrie 48. The rock shafts 58 and (30 are provided with i lingers G4 vwhich form the bottom of the .can

`rier 48, and the rock shaft 621s provided with.

arms ('ty whichconstitute'the top of said. carrier 48. The rock shafts 58 and GO in addition to being provided with fingers 64, are also `provided 'with arms 68 `and 70, respectively, which perform the dual functions of guiding the .bundles into 'the carrier 48 as they are discharged fromthe Agrain binder and assist .in expelling said bundles when the shock forming arms 46 arereached The rock shafts 58 and (30 are normally held in position to retain the fingers 64 in closed position through the intermediary of segn'ieutal gears 72 and 74, which inter-mesh with segmental rears 7G and 78 mounted uponshafts 8O and 82' journaled in the end member 54 and controlled by cranks 84 and 8G nornially held by coil springs 88 and SEO, respectively, against' the curved chai'inel bars 44. Asthe-bundle carrier I8 reach-es the end of its backward and upward movement, Fig. 8, the cranks 84 and 8G are carried above the upper ends of the rails 34 against the action ofthe respective springs 88 and 90 as the bundle inits passage to the shocl; forming arms 4G, forces the lingers (it to open position. "After the [aussage ot the bundle the springs l88 and in) ininnnliaelv restore the cranks 84 and 8G to normall posh tion against the channel bars 44, the upper ends of which extend slightly above the up per ends 'of the curved rails S4 to ehecl; said arms 84 and 8G, as they move to normal position.

Then the carrier 48 is in position to receive a bundle from the grain `binder the lili) disposed above the channel bars tls, Figs.v

1 and o. The arin 94 is provided with an antiilfriction roller 98 which travels on the guide 96 and is raised thereby until the sha-tt 62 is rotated approximately one-quarrter ot' a revolution, in which position it is hen held by al stop 100, lined to the rock shaft G2, and a latch 102 pivotally mounted. on the yoke 52 and vieldably held .in the path ot said stop by a coil springv 104. The latch niechanisin holds the rock sha-tft (i2 in. the last-mentioned position until the carrier 48 travels to the end ot its baclnvard .movement and returns to initial position for another bundle, whereupon the latch 102 contacts a transverse bar 105 at the rear ends ot the channel bars 32. and is thus caused to release the stop 100. shail't 62 is then actuated by the spring 92 and opens the arrns 66 to receive another bundle. This inoven'ient ot the rock shaft (S2 also swings the arms 94 downwardly until. checked by the roller 98, contacting` the guide 96:

The bundle carrier 4S is relieved oit undue shock on reaching the ends of its travel by shock absorbers best shown by Figs. 28 and 24 and two pairs 106 and 108 ot which are placed at the forward ends ot the rails $30, while another pair 106 is placed adjacent to the rear-ends ot' said rails 10. The shock al'isorbers 108 consist ot' curved springs tired at one end to thc channel bars 212 and curved downwardly and forwardly through slots in said channel bars 32 to contact the rollers 49 and check the speed thcreoil before they contact the second set ot' shock absorbers 10G.y which consist of butters 10i). ruidos 111. rods 1.13 lixed to the bullers 109 and slidably arranged in the lguides 111, and coil springs 115 .interposed between the buil'ers 10S) and the guides 111.. its the rollers lli ronh 't the lniIlcrs 10) and compress the lsprings 115, they are prerentnd, 'from unduly rcboundinl;` on the recoil ol said spi-inps by the upturned ends 117 ot the springs 10S, which stop the bundle carrier 4S in proper position to receive a. bundle troni the grain binder.

The bundle carrier 4S is inoved backmirdly and upwardly by sprocket-mechanisin which pauses while said bundle carrier 48 delivers a bundle to the shock forn'iing arins 4G and returns to receive another bunrlhe rock y dle. 1n carrying` out said sprocket mecha- .nisni l employ a pair of endless sprocket lchains 11() running around sprocket wheels 112 and 114. rlhe sprocket wheels 112 are tiXedly-niounted upon a transverse shaft 116 journaled in bearings 11S provided with rearwardly extending rods 120 slidably mounted in guides 122 at the forward portion ot' the shocker. Springs `124 are inter posed between the bearings 118 and the adjacent guides 122 to take up slack in the sprocket chains 110. v

The sprocket wheels 11,4 are united by a tubular. shaft 1253 loosely niounted upon a transverse shat't 125 journaled in two oppositely-disposed t(gear cases 12. fixed to the rear.k portion ot the shocker 'traine and disposed at opposite sides ot the track torined by the rails 30, 2 and 6. Willen the shocker is in operation the shatt 125 is constantly driven :troni a. shatt D ot the grain binder, througrh a train oif spur `roars 121i and 129. a shaft 128. and-bevel Ls jcars 1B() and 132. Clutch inechanisin 1333 is provided tor stoppin@ the atoreinentioir ed train at. the option or' the driver of the grain binder. The shaft 128 is rendered flexible by universal joints 134 and a slip joint 135, jsiinilar to the joint 16T. Fig'. T, so that it may ccon'unodate itself to independent vertical movement between the `grain binder andv the shocker when trave".- ing `over uneven ground. i

A trip clutch is provided for causing the tubular shait 123 to, rotate with the shaft 125 and ell'iect the operationiot the sprocket mechanism. Said clutch is shown in detail by Fig. 23. and comprises a deze` 136 lixed to the shalt 125 a clutch lever 138 pivotcd to one ot the sprocket wheels 114, a laterally projecting roller 140 mounted on said clutch lever 1238, a springv 142 to press the vclutchlevei 138 towards the shatt 125.y so

that the rotary dog 136 niay engage the -roller 140, and a housing' 144j formed integral with one side ot one oil the sprocket wheels 114 and having;` a recess 146 in which the tree end ot the clutch lever 188 swings and the end walls oit which restrict the pivotal n'iovrinents ot said clutch lever. il detcnt 14T engaging one ot the sproclr'et wheels 114, Fig. S, prevents rctroe'radeV movement ot the sju'orlict mechanism. when the trip clutch is thrown out ol` gear.

'.ihcI clutifh lever lltl heldl in the lull line position shown by Fig. 213, by a detent 14S, so that the sprocket mechanism will pause during the interval tl at the bundle carrier 4S returns 'lroin its raised position, Fig. Fl. to the forward end ot the shocker to receive another bundle. The detcnt 148 is drawn into engagement to intercept the clutchlever 138 after each revolution of the sprocket wheels 114 by a coil spring 150,

@mmc/led 51.1y Ol@ end to said detent 148 and me i'at its opposite end to a pin 152 fixed to'the -f adjacent `side oft-he 'gear case' 127. Ynfthe '1 present instance"thesprocket wheels-114 are so proportioned that eachLrevolutionthereof will'eausethe sprocket chains 110'toftravel one-half revolution.

lThe detent 148 is-disengaged from the clutch lever'138 by a trip lever 154, asindicated by dotted lines, Fig. 23, to allowthe trip clutch to drive the sprocket mechanism.

"Said trip lever 154 isfactuated to disengage ranged in the'path of one ofthe yrotary arms l fi'oin the apron C into the carrier 48. r=Aifter the detent 148 from the clutch lever 138 as" a bundle is discharged from the grain binder 4into the1 carrier 148, by a cable 156 'and a' vcrank shaft 160, which -latter is provided at one end with a crank `162 to whieh'the for* avard end of the cable 156 is lattaehed,`and' atA its opposite end withl a crank v'164 ar- E -of the grain binder which kickthe bundles beingactuated by the -arm E the crankshaft 160 is restored to normal position'by acoil-r spring 161and a cable 168, Figs. 1'l and 6.

` The shaft 160 like the'shaft `128-isrendered `flexible by universal ljoints'166 and a'slip joint '167, whereby'y it-may lengthenv land shorten topermit independent "vert-ical movement between'the grain binder and the shocker in passing over uneven ground;y

The shaft 160 is high enough toallow rthe vcarrierf48 to freelypass thereunder.

The parts remain in: dotted-line position,A

Fig. v28, asthe loaded 'bundle' carrier 48 is forced backwardly and'upwardly'by a set of dogs 168anda follower 170. 'Two sets of dogs 1'68andtwo1followers 170 are provided fin thepiesent instanceand vthe two sets of dogs are spaced to equally dividethe 'two `sprocket chains into two parts. t Each set ofrdogs -168^is pivotally mounted upon a transverse rod 172 fixed in 'ears 174 on the sprocket chains 110. As the-dogs168 Yare carried backwardly by the chains 110 they engage studs 180 projecting from the end members() of thercairier 48v and force Asaid Acarrier to within a short distance of with the studs 180, the bundle carrier 48 is l'orced to the Icud of its backward and up-k ward travel by the adjacent follower 170 which engages the vlowerportion of the bundle in the carrier 48 and in'continuing its movement forces saidbundle to open the fingers 64 and pass' 'between two sets of upper packers 184 and two sets of lower packers 185,-liereinafter described in 4detail Ik'and which fo'rcethe bundle into the shockforming arm V46. A'spaced a'slioi't 'distancev behind eachset of Each follower 170 is -dogs 1.08. 'siln'iilarin' construction tothe dogs A168 and `A`each vrconsistsof twoangular end members "186, AFig.'i26, united by a transverse inem- -ber 188 pivotally mountedupon af shaft 190 connected to'ears on the sprocket chains 110. TlieshaftlQO is provided at its ends with ing gear case 127.

Almost immediately after the dogs `168 rock out of engagement The followers 170 are somewhat rollers`194, which traverse the upper surface of vthe'longitudinal frame members 2A and one of which engages the triplever 154,

ithrowingit out of engagement with thel de- `Jtent 148, tliusstopping the sprocket mechani'sm after the chains 1101have made ahalf revolution and until the carrier 48has received another bundle from the grain binder. yWhen the sprocket mechanism stops, the succeeding set ofA dogs 168 are in Vposition' to` move the carrier 48 backward and upward with said other bundle.

The bundle carrier 48 is restored to initial position to receive the bundle, through the r fixed at one end/to the shaft 200 and at its opposite' end to the adjacent bearing 202.

Referring now in detail tothe upper set of' packers 184, which cooperate with the followers 170 and are disposedy at opposite sides 'oftlie passageway through which the bundles pass to the shock-forming arms 46, each set consists of two packers 184, Figs. 8 and 12,-which are actuated by the dia- Linetrically-opposed cranks 207 at the upper end of a shaft 208 journaled in the associate frame members and 42 and the underly- The rear ends of the packers 184 are connected to links 210 'pivoted to stub yshafts 212 depending from the adjacent frame members 38. As the crank shaft 208 rotates an alternatingl forward `thrust movement is imparted to the packers 184. 'Each shaft 208 is driven from the transverse shaft 125 through bevel gears 214, 216.218 and 220, Figs. 14 and 15. y

The lower packers '185, Figs. 8 and 18. like the upper packers V184, are arranged inl two sets disposed at opposite sides of the passagewaythrough which the bundles pass to the shock-forming arms 46. lllaeh set of packers V185 is given an alternate loiwvard thrust movement through the internicdiaey of the diametrically opposed cranks 224 at the upper end of a shaft 226 journaled in the associated frame member 42 and underlying 4gear case 127. Each shaft 226 is drivenfrom the adjacent shaft 208 through atrain. in theiassociate gear ease 127, Figs. 14 and 15.-comprising a trip clutch 228,21l spur 'gear 230 integral with the underside of the housingv 232 of said trip clutch 228, an

lll)

intermediate spur gear 234, and a spur gear 236 which latter is fixed to the lower end of the shaft 226. rlhe spur gear 230 and the housing 232 are loose on the shaft 203, but are driven at the proper time by a dog 233, fixed to said shaft 206,`and the roller 240 on a clutch lever 242 pivoted in the housing 232 and yieldably pressed toward the dog 233 to carry the roller 240 into the path tlun'cof by a spring 244. The pivotal movement of the lever 242 is limited by the end walls of a recess 243 in the periphery of thel housing 232.

The respective trip clutches 223 are alten nately thrown out of gear to stop the-packers 135, by detents 250, which latter are yieldably forced against the peri pheries of the housings 232 by springs 252 to engage the free ends of the respective clutch levers 242 and force them inwardly until the rollers 240 are thrown out of engagement with the rotary dogs 233. Then the respective trip clutches 223 are thrown out of gear the packer shafts 226 are held from backward rotation by pawls 229 and ratchet wheels 231. The detent 250 in the gear case 127 at the right side of the shocker (looking forwardl is controlled by a. trip lever 254 to which it is connected through the intermediacy of a cable 256 and a coil spring 253, Figs. 1 and 6.'

The trip lever 254 is mounted upon a shaft 255 and constitutes a part of the following described packer control mechanism: 259 designates a roller for intermittently actuating said trip lever 254. Said roller projects laterally from a spur gear 260 loosely mounted upon a rock shaft 262 journaled 1n a 264, 20 to 22, inclusive. The spur gear 260 is driven at intervals from a shaft 272 through a train located in the case 264 and consisting of a trip clutch 274, a spur gear 276 integral with said trip clutch 274. and an intermediate spur gear 273. The triii clutch 274 is of the same type shown by Fig. 22. and hereinafter described in detail. Said trip clutch 274 and the spur gear 276 are loose upon the shaft 272, but are caused to rotate therewith at intervals through the intern'iediacy of a rotary dog 230, fined upon the sh aft 272 and adapted to engage a roller 232 projecting laterally from the clutch lever 234.

The clutch lever 234 thrown out of gear with the dog 230 after completing each revolution by a detent 290, which is controlled hv a cable 294 attached to the crank 162 of the shaft 160. Backward rotation of ythe aforementioned train of gearing is prevented when the trip clutch 274 is thrown out of gear, by a ratchet wheel 296 fixed to the spur gear 260, a pawl 293 mounted upon a pin 30() lnfojecting inwardly from the case 264, a pawl 302, and peripheral ratchet teeth 304 en the peri phory of the trip clutch 274.

The packer shafts 208 and 226 on the left side of the shocker are driven by gearing in the associate gear ease 127, which is a dupli. cate of the gearing mounted in the case 127 at the right side of the shocker, excepting that it is driven in a reverse direction by a bevel gear 214 on the left side of shaft 125, to drive the associate shafts 20S and 226 in opposite directions from those on the right hand side and actuate the packers 185 accordingly.

The detent 250 in the left gear case 127 is thrown out of engagement with the associate clutch lever 242 by a cable 306, which is connected at its outer end to the crank 308, F ig. 6, at one end of a transverse rock shaft 310, journaled beneath the frame members 2 and provided at its opposite end with a crank 312 to which a trip lever 314 of the packer controlling unit is yieldably connected through the intermediacy of a cable 316 and a coil spring 313. rlhe trip lever 314 is mounted upon the shaft 255 and extends downwardly into the path of a roller 320 on the opposite side of the spur gear 260 from the roller 259. rllhe rollers 259 and 320 are diametrically disposed on the spur gear 260, as shown by F ig. 21. lVith the foregoing mechanism arranged as shown and described it is apparent that as the spur gear 260 makes a half revolution it will actuate the` lever 254, which, through the intermediacy of the intervening mechanism, stops the packers 135 at the right side of the machine, and on making another half revolution will actuate the trip lever 314, which, through the intermediacy of the intervening parts,

`will stopthe packers 135 at the left side of the machine, thus insuring the alternate operation of said packers 185, so that one set will move one bundle towards the right side of the shock-forming arms 46,`while the other will move the following bundle to the left side of said shock-forming arms and thus properly distribute the bundles and insure a symmetrical shock.

The shaft 272 .is constantly driven from the shaft by sprocket wheels 322 and 324, respectively, and an endless sprocket chain 326.

During` this time a roller 434 following the roller 842 on the ratchet wheel 386, raises the detent out ot' engagement with the clutch lever 348, so that ihe trl p clutch 850, throiurh the intermediacy ot the hereinbetore described trains olf gearing' andv a roller 486 Yfollowing the roller 868 on the large spur gear 866, trips the lever 356 which sets the bindinghY mechanism .in operation to bind the two cap bundles together by disenc'agiiig` the detent 378 from the trip clutch 380.

As the bundles lfor forming` a shock are forced, into the shock-ibrmingr arms 46 the lower ends of said bundles pass upon an endless conveyor 450 provided at intervals with transverseslats and reinforced at its niargins with endless sprocket chains 454. ',llhe endless conve 450 travels around rollers 456 and 458 mounted in the forward and rear ends, respectively,'ot a dump plattform 460 terminating` at its rear end in two runners 461. The rollers and 458 are provided with sprocket teeth "f2 and 464 around which the sprocket chains 464 travel and are driven by theV sprecliet teeth 4.62. 'lhe forward roller is also journaled in bearings 465 fixed to the transverse iframe member 4, and thus supports the dump platform 460.

During the time that the shock-forming arms 46 are being supplied with bundles for a shock the endless conveyer 456 is intermittently actuated to carry said bundles backward and assist the packers 184 and 185 in packing the bundles in said shock-forming,r arms, by a ratchet wheel 466 mounted upon one end olf the roller 456, a pawl 468 'for rotating; said ratchet wheel 466 step by step, a lever 470 rockably mounted upon the roller 46 and carrying the pawl 468, a disk 472 lixed upon one end ol.E the shaft 125, and a pilnian fli4l for transinittiiigg,- motion from said disk 472 to the lever 470, 1 and 2.

A'lter the shock has been completed and bound and the two cap bundles have been llorced into the shock-forming` arms 46 against the bound shock, said arms 46 are si'iddenly opened by mechanism hereinafter described, the speed of the endless conveyor is accelerated and the dump plattform 460 is lowered until the runners 461 travel upon the ground 'to discharge the shock and the two cap bundles in a standingposition..

The speed of the endless conveyer 450 is accelerated as stated by a train of gearing' consist/iner ot a bevel gear 476 fixed to one end ot the i'or\`vard roller 456, an interineshinny bevel rear tired to the upper end elE a shalt 480, a small spur gear 482 fixed to the lower portion ot the shaft 480, an intermeshing large gear 484, and a pinion 486, Figs. 2 and 1T te 19, inclusive.

The pinion 486 is rigidly mounted upon a trip clutch 488 o'lE the same construction and operation as the trip clutches hereinbetore described. The trip clutch 488 isloosely mounted upon the lower portion et the lefthand packer shaft 208 and is driven by a dolg;` 490 'ixed to the lower end oi said packer shaft 208. During the period i that the shock is being formed and the cap bundles are being supplied to the shock-forming arms 46, the trip clutch 488 and its minion 486 remain idle, the clutch lever 492 and its roller 494 being' held out ot gear with the dog 490 by a detent 496 pivoted to a supporting member 498 seemed to the underside ot the associated gear case 12T and the adjacent portion ot the shocker trame.

The detent 496 is heldin the path of the clutch lever 492 by a coil spring 500 until the needle actuating mechanism hcreinbefore described is thrown into play to bind the shock, whereupon the detent 496 is drawn out otl the path of the clutch lever 492 through the intermediacy of a cable 502, a crank shaft 506 to which said cable 502 is attached, and a cable 510 attached to said. crank shaft 506 and the segmental gear `428 ot the needle actuating mechanism.

The crank shaft 506 is mounted in 'the two left traine members 40 and 42 and is best shown by Figs. 12 and 29. After the detent 496 has been drawn out of the path or the trip clutch 488 as stated, the latter is then driven one revolution by the dog 490, during which time the detent 496 isY permitted to be drawn by the spring 500 into the path of the clutch lever 492 to stp the trip clutch 488. As the trip clutch 488 makes -the revo-- lution above described, it carries the pinion 486 therewith, which, in turn rotates the large gear 484 a partial revolutioiuor until the forward end ot' a cani 512 on the underside o'f said large 'cog wheel 484 approaches the end 514 oit the detent 496. The parts then remain stationary until the two cap bundles are bound together, whereupon the detent 496 is again drawn out ot the path of the clutch lever 492. The trip clutch 488 is then driven by the dog 490 and drives the pinion 486 which in turn drives the large cog wheel 484.

As the large cog wheel 484 starts on the remainder of its revolution the cam 5112 engages and holds the detent 496 out of the path of the trip clutch 492, aiter which it i passes out of engagement with said detent 496 and permits it to be thrown into the path'o'f the clutch lever 492 to stop the same by the spring :300. During' the period that the large con; wheel 484 is eoinpletin gl its revolution as above stated it drives the and throughthe intermediacy oit thetrai'n connecting it to thevrollcr 456, accelerates the speed et' the endless conveyer 450,: as..

sinallgear 482 and o'lV larger diameter and i thereby pushes said gear 482 out ot mesh with the largecog wheel 484.,.so that the. ratchet mechanism 466, 468 -may resume its operation ot driving the endless. conveyer 450 step by step during` thee-building ot an other shock. To allow tor demeshing o'i the gear 482 .trom the gear .484, the shaft't 480 is loosely mounted at its upper lend in a bearing 498` and at its lower end. in a slotsV The 495 ot the suiviportingl element lower end ot'- tlie shaft 480 is pressed toward thelarge gear 484 by a rod 497. operating in a. guide 4989, and a coilspring .501 interposed between the guide4 v499v and a nut. 508- threaded upon one end of the.` rod 497,

Then the-speed ot the `endless conveyer 4.50 is accelerated above described7 the platformi460 is lowered .until the runners deliveryof the shock and the. two cap bundles. Lowering .ot the platform 460 is ef` tected as follows: The large cog wheel` 484 has -a grooved` cam 52() at. its upper surface provided with `a concentric vportion and an opiviositelyrdisposed,y irregular -portion- 524. A roller 528 is disposed within the cam 520 and mounted upon one teind ot a lever` 550 vfulcrumed at -r5821011y a stud depending from the underside et `the lettkhand gear. ease 127. Said lever 580 is connectedto a toggle and a link 536, Fig. 17.1 Two Cables 538-are connected attheir forward ends to said `link 586 and at their Arear ends: i

to arms 540 secured to opposite sides ot the plattorn'1-4ti0 and. rein'torcedby braces 542. 'In their passage from the link 58Gto they arms 54.0:the cables runcver sheaves 548, 544, 546.. and 548 at opposite sides ot the shocker frame.

As the irregular portion .524 of the, groored cani*r 520` passes into engagement with the roller 528 fit swings the lever 580 upon its fulcrum and towards the cable 588 so that the same may run over theguide sheaves labove described and permit -theplat forni 460 to move downward byiits ownv the platform 4G01 isflfully raised and the;
